In this paper are compared two models of energy losses: that suggested by Prof. Paszota, Z. in monograph “Energy losses in the hydraulic displacement motors – definitions and relations serving the evaluation of the efficiency of hydrostatic drive” [18] and that of Prof. Balawender, A. in “Energy analysis and methodology of testing of low-speed hydraulic motors” [1]. By using the data obtained from the tests of SWSB-63 hydraulic motors [2] the graphs which illustrate mechanical, volumetric and pressure losses in function of the parameters on which the losses directly depend [18 ], have been elaborated and showed in comparison with the description of such losses in function of the parameters assumed in [1]. The below presented text has been complemented in relation to that published in the monograph [4] and read during the scientific technical conference „Cylinder 2010” organized by the Mining Engineering Centre „Komag”, Gliwice, and held on 20÷22 September 2010 in Rytro, Poland.
